摘要： PURPOSE:To automatically determine the optimum course in a sea area, by inputting information of changing course and narrow-area course or avoiding-course steering information in a local sea route to an optimum sea route determining section and necessary/unnecessary information of a change in shipping service to a wide-area sea route determining section. CONSTITUTION:The optimum sea route is determined V by storing a shipping service plan (a), recommended sea route (b), and other information in a file 1 and utilizing the information stored in the file 1 by a wide-area sea route setting section II. When information 24 regarding danger or change in sea route does not exists, an automatic steering command is outputted VI. When danger information 2 is inputted after the optimum sea route is determined, the presence/absence of the danger is discriminated and the discriminated results are inputted to a local sea route setting section IV and narrow-area sea route setting section III. Operability for avoiding the danger of a collision and stranding and steering and sea worthiness of the hull state to a rough voyage are determined at the setting section IV and avoidance of a typhoon and a navigation restricted area and an economical sailing speed are set in the setting section III. Thus the optimum sea route is determined and inputted to a steering device 23 through the output section VI. When this constitution is used, sea route determination which has been made by a captain can be determined automatically in the optimum state.

摘要： PURPOSE:To make it possible for a vessel to navigate automatically on a safe scheduled route and avoid striking a rock, colliding with a stationary-matter mark/another vessel by controlling in such a way as to have the optimum steering angle and the optimum main engine revolution-number so that a slippage between a position on the proposed route at the present time and the present position by means of a detecting signal becomes below a predetermined value. CONSTITUTION:On the basis of the navigation information of other ships' speeds, bearings, courses, or the like and the location information of stationary-matter marks of reefs, stationary buoys, or the like, the shortest scheduled route and a scheduled passing time at each point on a scheduled route from the starting point to a target point are led out by means of a scheduled route leading-out means 1. And such optimum steering angle and optimum main engine revolution-number as make a slippage between the present position detected by a position detecting means 5 on the basis of signals from a gyro compass 2, a log 3 or the like and the position on the scheduled route at the present time less than a predetermined value are led out respectively by means of an operating means 6. And a steering engine and a main engine are so controlled as to have the optimum steering angle and the optimum main engine revolution-number thus computed, when a vessel navigates each point on the proposed route with a minimum of slippage without colliding with another ship.

摘要： PURPOSE:To avoid the collision of ships by making it possible to rapidly discriminate whether collision is likely to be present, by calculating the time zone based on the advancing course and navigable circle of an own ship and those of an other ship. CONSTITUTION:On the basis of the data of the present position A, course and speed of an own ship, the data of the present position B, course and speed of other ship and the data of navigable circles 2a, 2b of both ships each having a distance enabling both ships to safely pass each other as a radius, not only scheduled times t1, t2, when the respective navigable circles 2a of the own ship before and after the own ship traverses the advancing course 1b of the other ship are contacted with the advance course of the other ship, are calculated but also the scheduled times t1', t2' when the respective navigable circles 2b of the other ship before and after the other ship traverses the advancing course of the own ship are contacted with the advance course 1a of the own ship are calculated and, by judging whether the time zone from the time t1 to the time t2 overlaps with the time zone from the time t1' to the time t2', the likeliness of collision is discriminated. By this constitution, the presence of collision is rapidly discriminated by relatively simple operational processing to make it possible to avoid collision.

摘要： PURPOSE:To improve the sailing safety of ships by calculating both the most approximate distance TCPA and the time DCPA against all underwater obstacles in case a ship veers in all directions at 360 deg. and comparing these TCPA and DCPA with the limit TCPA and limit DCPA respectively to obtain a navigable sea area including plural underwater obstacles in the form of the azimuth information. CONSTITUTION:The time DCPA needed for targets P1-P4 have their shortest distances and the most approximate distance TCPA are plotted by means of a variable phi. Then the limits DCPA and TCPA are set and plotted. If it is decided that a dangerous target exists in the present navigation course, a veering enable azimuth area having a range exceeding the limit DCPA is pointed out. In case no azimuth is obtained to exceed the limit DCPA of each target, the target having the margin of the TCPA in a certain azimuth is temporarily neglected. Then an azimuth is set again in the next step. Thus all simulating actions are performed when the dangerous position information is obtained to decide a navigable azimuth in a sea area including the underwater obstacles.

摘要： PURPOSE:To conduct automatically a safe and economical vessel-steering by leading out in a short time the optimum steering angle to be used and a course-change starting point on the basis of relations with a steering angle and course-change angle computed previously and the position of a reaching point and a vessel-speed or the like at a time of changing a course to a vessel's target course. CONSTITUTION:Relations with a steering angle and a course-change angle psi at every predetermined angle respectively, the position of a reaching point R' against an origin O at a time of turning to a course on which a bow direction is decided on each course-change angle, and a vessel-speed or the like are previously computed. And among each reaching point thus computed, each reaching point corresponding to the course-change angle which decides a target course L is selected and a route to each reaching point R' selected from the present position of its own vessel as an origin is each approximated in an ellipse. And on the basis of the steering angle and a tolerable bias gamma corresponding to each reaching point, the position of each reaching point and each ellipse route, the optimum steering angle to be used and a course-change starting point are led out, on the basis of which vessel-steering is conducted. At this time, the optimum steering angle to be used and the course-change starting point are led out in a short time on the basis of relations with the steering angle and course-change angle previously computed and the position of the reaching point and the vessel-speed or the like.

摘要： PURPOSE:To facilitate the setting of a course and to sail a ship by the shortest distance by substituting the spread of an obstacle in a sea area with a set section of grating-shaped measures and selecting a shorter course between courses which are circumscribed and has the smallest number of inflections. CONSTITUTION:The sea area from a present position P0 to a target position P1 is sectioned in a grating shape of measures which have one division of a minimum turn radius corresponding to a specific sailing speed. The spread of the obstacle 1 is substituted with a set of sections 5. Then, two courses which extend from the current position P0 to the target position P1 while circumscribed with the set of sections 5 and have the smallest number of inflections, i.e. P0-P6-P7-P1 and P0-P10-P11-P13-P1 are set and the right-side shorter route is selected. Consequently, the setting of the course is facilitated and the ship is sailed by the shortest distance while avoiding the obstacle.
